Creates a new GtkDialog with title title (or NULL for the default title; see gtk_window_set_title()) and transient parent parent (or NULL for none; see gtk_window_set_transient_for()). The flags argument can be used to make the dialog modal (#GTK_DIALOG_MODAL) and/or to have it destroyed along with its transient parent (#GTK_DIALOG_DESTROY_WITH_PARENT). After flags, button text/response ID pairs should be listed, with a NULL pointer ending the list. Button text can be arbitrary text. A response ID can be any positive number, or one of the values in the GtkResponseType enumeration. If the user clicks one of these dialog buttons, GtkDialog will emit the GtkDialog::response signal with the corresponding response ID. If a GtkDialog receives the GtkWidget::delete-event signal, it will emit ::response with a response ID of #GTK_RESPONSE_DELETE_EVENT. However, destroying a dialog does not emit the ::response signal; so be careful relying on ::response when using the

GTK_DIALOG_DESTROY_WITH_PARENT flag. Buttons are from left to right,

so the first button in the list will be the leftmost button in the dialog.

Here’s a simple example:

 GtkWidget *main_app_window; // Window the dialog should show up on
 GtkWidget *dialog;
 GtkDialogFlags flags = GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT;
 dialog = gtk_dialog_new_with_buttons ("My dialog",
                                       main_app_window,
                                       flags,
                                       _("_OK"),
                                       GTK_RESPONSE_ACCEPT,
                                       _("_Cancel"),
                                       GTK_RESPONSE_REJECT,
                                       NULL);
